I am trying to create a Bell Curve using Excel in regards to our Performance Reviews. Our reviews can be rated from 0-5. From our data I have calculated the mean to be 3.609, the median to be 3.79 and the standard deviation is .79. FYI the hightest score was 4.58 and the lowest was 3.0. Please show me how to chart this so that it makes sense!
Thank you!
